How To Write A LetterRead →What Are the Parts of a Formal Letter Format?
A formal letter has six standard parts arranged in order: the sender's address, the date, the receiver's address with title, the subject line, the body of the letter, and the signature. Following this conventional structure strictly maintains professionalism and ensures the reader does not miss any key information in your letter.
- Sender's address
- Date
- Receiver's address
- Subject
- Body of the letter
- Signature
Sender's Address
The formal letter must begin with the sender's address, written in the top right-hand corner of the page. The address mentioned must be correct so that the recipient may reply to the letter if required.
Date
The sender's address is followed by a date written in a verbal format instead of a numerical one. For example, if you are writing the letter on 12th February, you must write the date as 12th February 2026 and not as 12/02/2026. The latter may be acceptable in informal letters, but an official letter must contain a date written in word format.
Receiver's Address
After the date, the receiver's address is mentioned along with the authority title, like Sir or Madam, and their respective position, like The Editor or The Chief Officer. It is important to write the titles and positions correctly to denote proper respect for the authorities.
Subject
The receiver's address and the subsequent position details are followed by the subject line. The subject line must be written in a concise, formal manner and give a summary of the purpose of the letter. It works like a title or heading for the content; hence it must be relevant to the written content.
Body of the Letter
The body of the letter is the main content addressing the purpose of writing the letter and any other required information. It is written in official language with a professional tone. The first paragraph should introduce the purpose of the letter and the key points, with supporting details following in the next paragraphs.
Signature
The letter should end with a graceful note by saying thank you. Phrases like Yours Sincerely or Yours Faithfully are used: use Yours Faithfully when the letter begins with Dear Sir or Madam, and Yours Sincerely when you have used the recipient's name. After this, write the sender's name so the recipient knows who sent the letter.
